Wife on board issues...haaaa.
Tell her that the deal is: sex every night till death do you part or you get a Boxster and the sex is on her schedule.
Either way you grin and win, you'll get in great shape, and get your Boxster eventually.  
 
If she tries for option 1 then go with it hard till she is too worn out to carry on that way and then go get a Boxster. (Be sure to use strong condoms so this plan doesn't backfire on you 

)
